The fruit fly Drosophila melanogaster performs many behaviors, from simple motor actions to complex social interactions, that are of interest to neurobiologists studying how the brain controls behavior. Here, an undergraduate laboratory exercise uses cutting-edge methods to activate sets of neurons thermogenetically, triggering 60 different behaviors. Students learn how to recognize this large repertoire of behaviors from 16 fly strains that are publicly available, and from a large set of training videos provided here. A full protocol, timeline and handouts are included. Instructors need not have any experience working with flies. Student feedback is reported; in our experience, students are fascinated and highly engaged by watching animals perform such a broad array of behaviors. This exercise teaches fly husbandry and crossing, careful scientific observation, and principles of behavioral screening.
